1. Start by making a 210 * 260 px file. Create a new layer, select the Rectangular Marquee Tool, set a fixed size of 200px * 30px and place your selection in your document. Go to Select -> Modify -> Smooth and apply a 3px radius(be sure that your selection isn’t touching any of the borders of your canvas, if it’s touching them tehy will not be ‘smoothed’)
2. Zoom in your document and select the Rectangular Marquee Tool(without any fixed size), press Shift and hold it while you select the bottom rounded corner of your selection

3. Do the same thing to both bottom corners and fill your selection with #ff7f00

4. Now Ctrl+Click over the first layer thumb to select it, then create a new layer and go to Select -> Modify -> Contract and apply 1px. Now go to Edit -> Stroke and apply a 1px White(#ffffff) border.

5. Zoom in again and delete the bottom line of your border, and with the Pencil Tool, using White, fill the space between the border and the end of the orange thing(1px only)

6. Change this layer’s blend mode to Overlay and opacity to 50%

7. Create a new layer, select the Rectangular Marquee Tool and make a selection over the orange part like this

8. Fill it with White and change this layer’s blend mode to Soft Light and opacity to 35%

9. Repeat step 7 but making the selection a little smaller and placing it inside the other selection, change this layer’s blend mode to Soft Light and opacity to 25%
